Why, after every major accident and blunder, do we look back and say, How could we have been so blind? Why do some people see what others don’t? And how can we change? Drawing on studies by psychologists and neuroscientists, and from interviews with business leaders, whistleblowers, and white collar criminals, distinguished businesswoman and writer Margaret Heffernan examines the phenomenon of willful blindness, exploring the reasons that individuals and groups are blind to impending personal tragedies, corporate collapses, engineering failures-even crimes against humanity.
